Matinee and/or Sequence - Duration

Using matinee to do a fade in/out track, and, well, it would be beneficial to have a duration node that can be called. Currently I’m just using a Delay node, but that is a bit less of a modular solution, especially if I change the timing of the “cinematic”.

It is a feature that interest me too, for the same reasons.
Hope it will be added.
